Third-party user interfaces designed to generate an official HEScore must use the HEScore APIs and be approved by DOE. Standards regarding requirements for software inputs to the HEScore APIs are forthcoming. These standards will include a quality assurance process using standardized tests to validate that data entered into the third-party interface are properly converted to entries that produce the expected results from the HEScore APIs. Adherence to the official visual design and content of the label itself, as specified by DOE, also is required. Developers can begin with an Evaluation License, which generates an unofficial watermarked label for testing purposes. Once all requirements are met, permission to use the Production URL will be granted.  Please email  if you would like more information.
